In Safeguard Base Operations, LLC v. United States, 2019 WL 3789887 (July 2, 2019), a protest to the U.S. Court of Federal Claims (COFC), the procurement was for dormitory services for the Federal Law Enforcement Training Center, U.S. Department of Homeland Security. The agency rejected an initial proposal because the submitter (and eventual protestor) failed to include in its price proposal several government-supplied “plug numbers”—i.e., pre-priced items for two contract line items (CLINs) X007AA and X007AB from the solicitation schedule.
